7NG0350-0BA01-0CF0-ZE27 SIEMENS Exclusive SITRANS TF320 Temperature Transmitter Original Brand New

The SIEMENS 7NG0350-0BA01-0CF0-ZE27 SITRANS TF320 is a highly reliable and versatile temperature transmitter designed for industrial applications where safety, accuracy, and durability are critical. Built with a robust die-cast aluminum dual-chamber enclosure, this unit is suitable for wall or pipe mounting and delivers excellent performance even in challenging environments. With its flameproof (Ex d) / explosion-proof (XP) housing and NEPSI certification, the SITRANS TF320 ensures dependable operation in hazardous areas while maintaining the highest level of protection for both personnel and equipment.

This temperature transmitter supports a configurable input, including RTD Pt100 in accordance with IEC 60751 standards, and offers galvanically isolated two-wire output with HART communication (4–20 mA). The design guarantees stable measurement results, while its cold junction compensation and signal linearization features enhance accuracy for both RTD and thermocouple sensors. The transmitter continuously monitors input signals and can automatically detect sensor errors, short circuits, or interruptions, thereby minimizing downtime and improving process reliability.

Overview

The SITRANS TF320 is a two-wire transmitter available with or without HART protocol. It provides a universal input compatible with virtually any type of temperature sensor, making it ideal for flexible integration across different industrial processes. Configuration can be performed via PC, HART communicator, or optional local operation, ensuring user-friendly setup and fast commissioning.

Function

With HART V7 communication, parameterization is straightforward using SIMATIC PDM software or a hand-held communicator. For versions without HART, configuration can be performed with SIPROM T software via modem. The device supports both analog 4–20 mA output and digital transmission for diagnostics and real-time monitoring. Test terminals allow direct measurement of the output loop without disrupting current flow, simplifying maintenance and calibration tasks.

Principle of Operation

The SITRANS TF320 amplifies and linearizes input signals from resistance thermometers, thermocouples, ohmic sensors, or millivolt signals. Input and output are galvanically isolated to ensure reliable operation. The HART-enabled version offers additional digital communication, making it possible to conduct online diagnostics, configure settings, and transmit measured values directly. This robust combination of analog precision and digital intelligence makes the SITRANS TF320 a trusted choice for modern industrial applications requiring consistent accuracy and safe operation.
